Model-based testing (MBT) seems to be technically superior to conventional test automation. However, MBT features some difficulties that can hamper its deployment in industrial contexts. We are developing a domain-specific MBT solution for graphical user interface (GUI) testing of Symbian S60 smart-phone applications. We believe that such a tailor-made(More)
Formal methods are making their way into the development of safety-critical systems. In this paper, we describe a case study where a simple 2oo3 voting scheme for a shutdown system was verified using two bounded model checking tools, CBMC and EBMC. The system represents Systematic Capability level 3 according to IEC 61508 ed2.0. The verification process was(More)
—Many commonly used systems, for example event-based systems, can be considered action systems. Traditionally, action systems have only been visualized behaviorally using state diagrams, which requires translating the system into a state machine and discarding structural information. We introduce an action-based diagram and associated formalism that depict(More)
